GAME OF THRONES fans have a long wait for season eight, but it seems that one tiny detail may have already been leaked.

Kit Harington, who plays Jon Snow in the HBO fantasy, has returned to filming, and one eagle-eyed fan was at the airport to spot him.

The fan wrote on Twitter: “That moment you walk up to Kit Harington at Belfast airport; decide it’s not Kit Harington when you get close only to find out five minutes later that it was in fact Kit Harington.”

With Kit, 31, back in Belfast, it seems that he will be filming more scenes in The North as his heroic character takes the fight to the Night King (played by Vladimir Furdik).

According to fan site Watchers On The Wall, filming has already recommenced in Ireland.

Convinced fan, grumblepup, wrote on the forum: “Can anyone tell me if something similar happens in the books? I wonder if anything will come of it in the final season, now that the two characters could very possibly meet up again.”

“There are a lot of things cut out [in the show] that would seem rather inappropriate in some part due to her age (there’s even a scene where you can feel it a little), from him commenting on her beauty/body to getting a song from her at knifepoint and then weeping after she sings.

“Sansa also falsifies a memory where they kiss (but the moment she draws from it is from an unpleasant, traumatic one.”
